I'm sure this is not what your thread is asking but I've had it with buying the best.

In suspension parts or tools and most everything else. The best is usually about right.

For batteries. The best battery can be in a car you are selling, die from a light being left on and ruined if frozen or damaged.

I'd rather buy a battery for a good deal and would be very satisfied if it lasts longer than 6 years. Unless the hood is open and you have to look at the cheapness. Then it's Die Hard, Eliminator, Interstate or factory correct.
